APPARATUS FOR BLUESTONING SEED.

SPECIFICATION forming part of Letters Patent No. 677,992, dated. July 9, 1901. Y Application iiled April 22, 1901. Serial No. 56,954. (No model.)

To ctZZ whom, in' may oon/corn. v

Be it known that LANDREW J. JOHNSON,

buckle, in the county of Colusa and State of California, have invented a new and useful Apparatus for Bluestoning Wheat, of which the following is a specification.

My invention is an improved apparatus for bluestoning seed-wheat; and it consists in the peculiar construction and combination of devices hereinafter fully set forth andclaimed.

In the accompanying drawings, Figure 1 is a side elevation of'auapparatus constructed in accordance with my invention. Fig. 2 is a vertical sectional View of the same, showing the conveyer raised to'ahorizontal position. Fig. 3 is a similar view of the same, showing the conveyer lowered. Fig. et is a top plan f' View of the sanie.- Fig. 5 is an end elevation of the same.

In the embodiment of my invention I provide a tank 1, which may be either of the form here shown or ofany other suitable form and is of suitable dimensions. The said tank is .adapted to contain a solution of bluestone or any-other suitable liquid for treating seed-wheat. Over one end of thesaid tank is a draining-frame 2, which may be either of the construction here shown 6r any other suitable construction. On the sides' of said tank 1, at a suitable distance, from lone end thereof, which I will term the front end,are a pair of vertical standards 3, the upper ends of which extend abovethe sides of the tank..

Also on the `sides of the tank, at a suitable distance from the standards, are a pair of standards 4, which are somewhat higher than the standards. A shaft 5 is journaled in suitable bearings, with which the upper portions of the standards 3 are provided, and at the central portion of the said shafts is a roller G of polygonal form in cross-section. To one end of said shaft is attached a crank 7, by means of which said shaft and said polygonal roller may be rotated. A frame 8;which-in the form of my invention here shown comprises a pair Vof longitudinal side boards 9, is pivotally attached at one end to said shaft 5, the latter at the points intermediate of the ends of roller 6 and the sides of the tank passing through openings in the said sideboards 9.` Thereby the rear end of said frame 8 may be raised and lowered, so that said frame may be disposed in a horizontal position above the level of the liquid in the` tank, as shown vin Fig. 2, or inclined so that the rear end of said frame Will be submerged in the said liquid,

'11 of polygonal form in cross-section which corresponds in shape and dimensions with the roller 6. Arms 12 have their lower ends pivoted on the projecting ends of shaft 10, said A shaft 10 is journaled arms being disposed between the sides of the frame 8 and the sides of tank l. An endless traveling conveyer 18 connects the rollers 6 11. Thesaidendlesstravelingoonveyercomprises links 14, which are pivotally connected together at their ends by pins 15. The

Vsaid links are of such length as to be adapted to be engaged by the faces of the polygonal rollers and are preferably made of Wood.

A shaft 16 is journaled in bearings near the upper ends of the standards 4 and is offset to form a crank 17, which crank passes through vertical slots 18 near the upper ends of the arms 12.' Thereby by partly turning said shaftl the rear end ofthe frame -8 and endless traveling conveyer 13 may be raised and lowered. Said shaft/16 has a crank 19, by means of which/it maybe thus turned.

A frame 20 is disposed between the side boards 9 of frame 8 at a point in rear of the endless traveling conveyer, but proximate thereto, and said frame is pivotally connected at its lower side to said side boards 9, as at 21. Said frame 2O is provided with a series of rollers 22, which are revoluble in the sides of said frame. Said frame and said rollers constitute a retaining and engaging element,

as presently appears. The upper sides of said IOO frame 2O is moved forward and the same is caused to closely approach the rear end of said endless traveling conveyer, as is shown in Fig. 2.

The operation of myinvention is as follows: Initially the frame 8 and endless traveling conveyer are lowered to the position shown in Fig. 3. A bag of wheat (indicated at a) is placed between the endless traveling oonveyer and the retaining and engaging element. The bag` ot' wheat is hence partially or entirely submerged in the liquid. The endless traveling conveyer is then caused to operate in the direction indicated by the arrow in Fig. 3, and hence the links thereof by successive engagement with and passing under the lower side of the bag of wheat cause the latter to rotate, and thereby the bag of wheat becomes entirely saturated by the liquid. Continuing to operate the endless traveling conveyer in the same direction, the operator also turns the shaft 16 by means of the crank 19, and thereby causes the frame S, together with the endless traveling conveyer and the retaining and engaging element, to move upward, and hence lift the bag of wheat from the water in the tank and also cause the said retaining and engaging element to move forward, closely approaching the rear end of the endless traveling conveyer, and in so doing compress the bag of wheat between the rear portion of said endless traveling conveyer and said retaining and engaging element, and thereby cause the said bag of wheat to be engaged by the conveyer and carried forward on the upper lead thereof tothe fralne 2, onto which the saturated bag of wheat is discharged by the said conveyer, and the said bag is permitted to remain on said frame while draining, as is indicated in Figs.2 and 3.

Having thus described my invention, I claiml. In an apparatus of the class described, the combination of a tank, an endless traveling conveyer, means to raise and lower one end thereof and means coacting with said endless traveling conveyer to rotate a submerged article in said tank, substantially as described.

2. In an apparatus ot' the class described, the combination of a tank, an endless traveling conveyer, means to raise and lower one end thereof, and a retaining and engaging element, the latter coacting with said endless traveling conveyer to rotate a bag of grain when said conveyer is lowered and to cause said bag of grain to be engaged by said conveyer when the latter is raised, substantially as described. y

3. In an apparatus of the class described, the combination of a tank, an endless traveling conveyer therein, a pivoted retaining and engaging element mounted in the frame of said conveyer in rear of the endless traveling element thereof, a revoluble element, connections between the latter and said conveyer to raise and lower the latter, and connections between said revoluble element and said pivoted retaining and engaging element, to move the latter toward the rear of said endless traveling element as the latter is raised, substantially as described.

4. In an apparatus of the class described, the combination of a tank, a draining-frame at one end thereof, an endless traveling conveyer having one end pivotally mounted in said tank, whereby the rear end of said conveyer may be raised and lowered in the tank,
